Broken Object Level Authorization (BOLA). API security focuses on common threats like BOLA, excessive data exposure, and broken authentication.

Answer

Local fiber optic cable breaks

Answer

Standard server hardware failures

Question 10

A security architect is designing a SOC response workflow using Cisco SecureX Orchestration. Which mechanism is most effective for automated remediation of an endpoint identified as compromised via Cisco Secure Endpoint?

Accepted Answer

Triggering a workflow that executes the isolate endpoint action in Cisco Secure Endpoint via API.. Cisco SecureX Orchestration uses workflow automation to link threat intelligence from Secure Endpoint to automated containment actions like isolation.

Answer

Deploying an umbrella policy change to redirect the host traffic to a sinkhole.

Answer

Configuring a local script on the Cisco ASA to block the host IP address.

Answer

Using Cisco Defense Orchestrator to push a new access control policy to the endpoint.

Question 11

An organization experiences a surge in successful phishing attacks. The post-incident architecture adaptation requires automated email analysis. Which Cisco product provides the necessary API for integrating email sandboxing data into a SOAR platform?

Cisco Secure Email API.. Cisco Secure Email (formerly ESA) offers extensive APIs for extracting threat intelligence and sandboxing results from Advanced Malware Protection (AMP).

Answer

Cisco Firepower Management Center REST API.

Answer

Cisco Defense Orchestrator API.

Answer

Cisco Identity Services Engine ERS API.

Question 12

A security architect is developing a requirements document for a SOC. Which Cisco capability allows the SOC to prioritize alerts by correlating threats across network, endpoint, and cloud?
